Expose the joint trajectory controller verbose setting as a parameter

[bmagyar]

This is something I think should be documented well. The verbose parameter there is for advanced use as it breaks real-time safety by using ROS logging services. I would not "open it to the public" as a parameter. In it's current state there has to be a strong need to go debugging the controller and the one seeking it will find it.

What do you think?

What do you think, gentlemen? @graiola @ipa-mdl

That seems reasonable, totally fine if you want to pass on this.

Maybe you could still change this PR so that instead of opening it as a param, you add a comment in the code to explain that the verbose flag possibly breaks realtime-safety.

[bponsler]

I'm fine with adding a comment, but I would suggest also displaying a runtime warning to the user whenever the verbose flag is enabled to help prevent someone from accidentally leaving the flag enabled.

Thoughts?

There is a failing test on travis due a timeout but this code it only affecting a print. Merging...
